摘　　要：在应用程序功能设计的过程中,通常需要设计数据记录查询功能。一般来说,查询因不同的数据集而体现不同的检索条件和不同的结果集;有时即使有相同的数据集,但因应用需求、地点或者时间的不同,其检索条件和结果集也会有所不同,有时还需要保存这些频繁使用的检索条件。能够综合处理这些情况而形成的应用程序则会具有更加强大的生命力,本文论述在Delphi 2007开发环境下的通用查询功能的实现技术。During the process of the function of the application program design, the function of data query is usually needed to design. Generally speaking, the retrieval conditions and the results of data query vary from different data collections. Sometimes, even if it has the same data collection, the retrieval conditions and the results are different because of different application demands, time and places. Sometimes, it needs to preserve the frequently used retrieval conditions. The application program, which is able to deal with these conditions comprehensively, has stronger vitality. This paper discusses the implementation technology of universal query used in Delphi 2007.
